Spain issues its first energy code in 1979, but it only covered the building envelope. The most recent code, Código Técnico de la Edificación (CTE), was first approved in 2006 and was subsequently revised in 2008 and 2010. The latest revisions to the energy requirements took place in 2013, when a number of corrections and supporting documents were issued. The code is internationally known for mandating the use of solar panels.

|Existing Code Coverage|
Local autonomous communities implement the code by checking construction plans and inspecting construction. In those jurisdictions that do not have enough resources, the Ministry of Public Works and Transport may step in. As in many countries, some jurisdictions may de facto have less review and inspection because of resource constraints.

Name of Software
LIDER and Calener
LIDER is a software application sponsored by the Ministry of Housing and the Institute for Energy Diversification and Saving of Energy (IDEA). LIDER is used to verify, temporarily and under certain technical conditions, energy demand requirements of the Basic Document DB Energy Saving HE Technical Building Code. Calener, is a tool which determines the level for a building energy efficiency for building EPC certificates.

|Penalties for non-compliance|
Fines for not having, displaying or presenting erroneous info for obtaining a certificate
|Incentives and Recognition program for compliance|
Spain offers several types of incentives to promote energy efficiency in buildings, such as capital grants for energy efficiency in buildings and low interest-rate loans.

When the new CTE was approved, the Ministry of Public Works and Transport and the Institute for Energy Diversification and Saving of Energy, representing the Ministry of Industry, organized training sessions in Spain’s 17 regions. The regions and engineer and architect associations provided CTE training courses, as well as a training course on the official software, LIDER (code compliance) and CALENER (energy rating software for new buildings).
|Building Materials Ratings|
Spain follows European Union building material standards, CE marking. CE marking is mandatory for all building materials and covers aspects of energy performance. The EU’s Enterprise Directorate General launched a program to standardize evaluation of construction materials for their energy and environmental qualities. The Association for Standardization and Certification develops technical standards and certification. The association maintains a website with numerous resources on these standards.
The energy performance certificate (called Certificado de Eficiencia Energética del Edificio) provides an estimate of annual primary energy consumption. The certificates also classify buildings based on CO2 emissions, where a new building meeting regulations is certified as C1, and existing building receive a C2 designation, which is further broken down into Classes A-G based on the modeled estimate of energy use. Certificado de Eficiencia Energética del Edificio, an annual primary energy consumption and a classification based on CO2 emissions, where C1 is relative to a modelled building meeting regulations, and C2 is relative to existing building stock averages, Classes A-G. The EPC is used to demonstrate compliance with the performance based building code. For new buildings they are enforced jointly. For existing buildings they can be enforced separately.
